Do we really scale 1088 to 1080? Surely we should truncate to avoid the detrimental effects of scaling. I know a lot of us have gone to some effort to buy a true 1080 display with defeatable overscan. Don't we lose any advantage of doing so if myth performs an unnecessary scaling?

I'd always assumed 1088 was really a misreported 1080 with no intention that the bottom 8 lines be displayed. Is that not the case?
